I assume you mean Gartley; I personally use fib. retracements for profit taking. 38,2 for T1 and 50% for T2.
If you want to know more about advanced patterns, and how to trade them, I suggest you take a look at the youtube channel of Akil Stokes from Trade Empowered.
Well, there is a big difference between a Bat and a Gartley. Especially when they are valid and where the optimal place is to enter these patterns. But i'm sure you will learn all of that on the youtube page I suggested. Note that these are my !personal! target approaches.
